Server Vehicle Database for Environmental Data Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems face challenges in accurately detecting dynamic objects in complex traffic situations, particularly in areas like intersections, due to limitations in sensor data interpretation and excessive data traffic between vehicles, leading to incomplete and outdated environmental data.
Innovation Solution
A method where a motor vehicle acts as a server, maintaining a centralized database of environmental data, which is updated by its own sensors and data from other vehicles, allowing for precise information sharing and reducing data traffic through motor vehicle-to-motor vehicle communication, enabling continuous and dynamic updates even when a vehicle leaves the area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If each motor vehicle maintains its own environmental data pool and exchanges data through requests, then the availability of environmental data is improved, but the data traffic between vehicles increases massively
Solution Approach 1:
Multiple environmental data pools from different motor vehicles are merged into a single centralized database that is maintained by one server vehicle. This consolidation allows all vehicles to access comprehensive environmental data through a single data structure, eliminating the need for multiple separate data exchanges and significantly reducing overall data traffic in the network.
Solution Approach 2:
A centralized database acts as an intermediary between the server vehicle and requesting vehicles. Instead of direct peer-to-peer data exchange, the database mediates all environmental data requests, storing and distributing information efficiently. This intermediary structure optimizes data flow and reduces redundant communication between vehicles.
2Measurement precision
If environmental data is exchanged between motor vehicles on request, then the precision of environmental information is improved, but the data is lost when road users leave the surrounding area
Solution Approach 1:
The server vehicle proactively maintains and updates the centralized database with environmental data before other vehicles need to request it. By continuously recording and storing environmental information in the database, the system ensures data is available and retained even when original data sources (road users) leave the surrounding area, preventing data loss through advance preparation.
Solution Approach 2:
The environmental data is copied from individual vehicle sensors into a persistent centralized database structure. This copying mechanism creates a redundant backup of environmental information that is independent of the original vehicles' presence, allowing the data to be retained and accessed even after road users have left the surrounding area.
3Quantity of substance
If a centralized database is maintained by one motor vehicle, then the data traffic is reduced, but the complexity of the system increases
Solution Approach 1:
The centralized database is designed as a universal data structure that can store and manage multiple types of environmental information from various sources. This multi-functional database serves all requesting vehicles with a single unified interface, reducing the need for multiple specialized data exchange mechanisms and thereby reducing overall system complexity despite the centralized architecture.
Data Source
AI summary
Data relating to at least the dynamic objects of the surrounding area is ascertained by sensors of at least one motor vehicle. The data is stored in a database provided by a motor vehicle, acting as a server for the surrounding area, which communicates with other motor vehicles. When a request message is received, the motor vehicle acting as a server transmits at least one part of environmental data in the database to the requesting motor vehicle and/or transmits a request message for transmitting environmental data, relating to the requested data about at least one object, to other motor vehicles to update the database and/or captures environmental data relating to the at least one object by other sensors. The database is updated to include the transmitted or captured environmental data.
